Figure 10 is a sectional elevation showing the method of controlling the contact of the exhaust' gases'with an intake manifold of 1 is an internal combustion engine and 2 95 and 3 are respectively the intake and exhaust manifolds.' 4 is a -usnal construction of fan in advance of the engine. 5 is the oil rectifying device located in rear of the fan 4 'and secured upon the pipe 6 which communicates with the exhaust manifold and adapted for the passage' of theexhaust gases. The body of the oil rectifyingdevicehas' vthel upper chamber 7v for receiving the oil 'to bel rectified, the lower chamber 8 below and communicating with the upper chamber l' 7 -for heating the oil and the 'condensing chamber-9 above the upper chamber 7. The

upper chamber 7 h-as the inlet 10 which is in `vertical passageway 16, a ported member 19 seating against the lower end of the tube and extending upwardly therewithin and having the 4central opening 20, a disk valve 21 lof cated within and movable longitudinally of the tube and 'having the peripheral projections 22 and the abutment member 23 seated against the upper end of the tube and exdisk valve andis provided with the vertical- 'minating above. the level of the voil in the tending downwardly therewithin and hav,- ing the central .opening 24. This abutment member limits the upward movement of the slots 25 in its lower portion for permitting the ow of oil therethrough when the disk valve is seated thereagainst. 26 is a suitable support having upwardly extending prongs engageable .with the ported member V19 for supporting this member, the tube and .upper abutment member within thepassageway. It will be seen that with this construction oil may pass upwardly through the ported member 19 raising the disk valve of this ported member, `pass between the main body of the disk valve'and thetube 18, through the spaces ali'orded by the projections 22 and then through the vertical slots 25 in the upper abutment member 23 and into the passageway 17, after which it enters the lower chamberS. The lower portion of the body of the oil rectifying device is provided with a flange which is adapted to be seated upon and secured to the upper wall of the pipe 6. The lower chamber 8 is formed by the lower portion of this body and vby means of thel shell 27 secured to the body and extending downwardlyV into the pipe 6. 28 is a bell-shaped partition in ihe lower portion of the lower chamber and hav# ing Vits vdepending 'anges terminating a slightrdistance from the side wallof the shell 27.' This partition forms with the bottom ,of the shell a space for highly heatingf the oil therewithin. 29 is a tube opening at its lower end into the yspace below the par,

tition l2 8, this tube extending upwardly through the upper portion 'oftthe lower chamber -8 and also throu-ghthe upper cham'- ber 7 and having an upper .open end ter- Vof the body'of the device.

To maintain the oil in theiu'pper chamber" 7 relatively cool, that portion of the body of the oil rectifying-'device having the upper its top spaced slightly fromthe top of the lower chamber and its side wallspaoed slightly fromthe side wall of the lower chamber. tending upwardly to the 'upper chamber 7 is also heat insulated by means of the tube32 That'portion of the tubes 29 eX-v surrounding aiid slightlyspaced from the tube 29 and extending' from. the bottom of the upper chamber to a point substantially even with the top of thetube 29.

lT0 freely Apermit the oil to enter'the lower chamber 8 the upper portionl thereof is vented by meansof the opening 33 in the tube 29, this opening communicating with the annular space 34 formed by the ring 35 which surrounds the tube 29 and holds the bell 31 in place; This ring has the kopening -36 therein for placing the annular space 34 in communication with the upper portion of the lower chamber. `37. and 38 are deflectors above the upper .chamber The' -deflector 37 fis located directly above the open end of the pipe 29 and the delector 38 is located above the deflector 37. The latter def-lector normally forms the. bottom of the condensing chamber and is lill) adapted tonormally seat upon the annular flange 39 ofthe body of theoil rectifyingV device and is held to its seat by means 'of the coil spring which surrounds the shoulder rivet 41 extending through the deflector 38 and carryingthe deile'ctor 37 and-carried in turn by means o'f the cover 42 upon the body of the oil rectifying device, 43 is a spreader in the nature of a shallow' cup mounted upon the upper end of thetube 29 and having upstanding legs'44 engageable` with the under side of the 'deflector 38 forholding the spreader in place. cated within the confine-s of .theup ber 7 and above the level of the oil ,therewithin and is adaptedvt-oreaeivethe oil, in-` cluding the foreignnilater'ial therein, after it passes upwardly through the tube 29 .and is deflected downwardly to spread this oil and allow the foreign material, such vas water and gasoline, to evaporate, the vapor then passing upwardly throughtlieibpenings 45 in the deflector 38 and iitcithe condensing the upper chamber 7 and commingles there- This spreader is lorper chami chamber. 9 after which it passes' outwardlyv f 'with prior to its discharge through the overflow outlet 12. y

ATo permit theoil circulating through the yupper chamber 7 and heating chamber when the temperature in the heating chamber is not sufficient to boil the oil `and eject the samefupwardly above the upper end ofthe tube 29, I have provided the ley-pass 46 in the nature 'of a tube extending'laterally from and communicating 'with the tube 29 and with the discharge nipple 47 of the bodyof the oil ectifying device. This by-pass is loeated'below the overflow outlet 12 and does not hinder the discharge of Athe oil and foreign materials upwardly through' the tube -29 under the pressure generated by heat when the4 latter is sufficient. f

For the purpose of collecting sediment, I have Aprovided at the inlet 10for the upper chamber 7 the'lter device 48 which ,has t-he line mesh screen or Filter 49 forming a transverse partition Within its chamber. This screen is provided in its upper portion with the opening 50 for the passageV of the oil when the latter has raised sutlieiently in the vchamber of the filter device. The pin 51 is preferably provided extending through the yopening 50 for locating the opening in the upper portion ofthe chamber. If desired, avalve .52 may also be provided surrounding vthe pin and adapted to close the opening 50, this valve being forced against the screen by suitable means such as the coil spring 53.

Toprovide a restricted opening in the i inlet 10,.there is the cup-shaped valve 54 located within this inlet and having the restricted opening 55 in its base. To maintain this opening free of sediment there is the pin 56 which is held stationary and which is .adapted to extend through .the opening v55 when the valve 54 is forced rearwardly by theoil passing through the inlet. The valve is normally held in predetermined relation to the pin by means of the coil spring 57. To variably control the flow of the oil passing through `the inlet 10 according to the pressure of the oil, the pin 56 is tapered 'so vthat as the valve is forced rearwardly the effective area of the opening 55 is gradually decreased. l

For the purpose of cooling the oil I have provided `the cooling device'58 preferably formed of a -copper tube and having theupstanding legs 59 and 60, the leg 59' being coiled around the leg 60. The leg 59 as shown in the present instance 4is connected .to the discharge nipple 47 of the body of the oil rectifying device and the leg 60 is connected to the crank caseof the engine. This cooling device is located in rear of the fan 4, whici directs air against and past the same. In the event that there is no flow of the oil through the cooling device or its flow is sluggish owing to-the oil being 'congealed, or for some other reason, oil may flow lsage ot' the exhaust gases.

through. the by-pass 61 which vis in the nature of a tube extending from the upper end portion of the leg 59 and into the upper end portion of the leg at a lower point. This tube preferably hasa portionv extending immediately adjacent to the pipe 6 to further increase the temperature the oil flowing therethrough. Thus it will be seen'that with this arrangement the voil may be cooled in the summer time or when hot and may be heated-in the winter time when cold so that a more uniformtemperature of the oil passing to the -working parts of the engine may be secured, regardless of the temperature of' the air.

As shown in the modified construction in Figures 6 and7 the air rectifying device has the same general arrangement of parts and communications with the exception that the heating chamber 62'in the lower portion of the body of the device does not extend downwardly into the pipe 63 adapted for the pas- Instead the shell 6l forming the lower portion of the heating chamber extends upwardly into` the body and the discharge pipe 65 leading from the heating chamber opens directly intothis heating chamber. "To lcontrol theamount of heat to which the heating chamber is exposed in this construction I have provided the thermo` staticcontrol device 66 which extends into the pipe 63 xand is in. heat conducting contact with the shell 64. This device comprises the stem 67. threaded into the ,shell and extending downwardly therefrom into the pipe. This stem is provided with the spaced lateral tins 68 preferably integral therewith. 69 is a cage surrounding the stem 67 of the heat conducting chamber and provided with the spaced lateral detlectors 7 0 which are connected together by the vertical ribs 71 carried upon the base 72, these l detlectors being adapted to laterally 'align with the tins 68. The base 72 is connectedl to the lower end of the thermostat.73'whieh is located within the stem 67 and is rigidly connected at its upper end to lthe stem.l lVith this arrangement as the vtemperature of the exhaust gases increases the thermostat expands, thereby lowering the cage'and moving the deflectors downwardly between the tins to restrict the flow of the exhaust gases pastthe tins. The heat is conducted from these fins-through the stem 67 'into the. shell., In. the modified construction' shown in Figure 8 the inlet Il inthe body of thevoil rectifying device hasI the restricted opening 75 opening into theupper chamber76 of this body. 77 is a vertically movable valve located within the inlet and` having the annuupon excessive pressure of the oil against lthe intakel manifold I have as shown in Figthe pressure of the coil spring 8 within and abutting the valve `to thereby shut off a portion of the opening 75 and restrict the effective area thereof. W'ith this construction it will be seen that the flow of the oil 'into the upper or oil receiving chamber is varied according to the pressurel of the oil passing through the inlet.

For the purpose of controlling the heat- 'inw of the lower or heatinor chamber ofthe body of the oil rectifying device by the ex' haust gases' according to the flow of these exhaust gases passing through the pipe 6, I. have provided as Shown in Figures 1 and- 9 particularly, the V-shaped deflector 81 facing the iiow of exhaust gases and located in advance of the heating chamber and spaced slightly therefrom.. This deflector is in the nature of a lug preferably formed integral with the pipe 6 and is so constructed that it tends to laterally deflect the. exhaustv gases from the heating chamber to a greater extent as thevelocity of these exhaust gases increases, thereby reducing the contact ofthe exhaust gases with the heating chamber as their` velocity increases. y 1

'To control the flow of the exhaustgases through the pipe -6 I have provided the pivotal valve 82, which is adapted to extend .partially across the-entrance end of the pipe or the discharge end of the exhaust manifold 3'. `'Ihisivalve is preferably connected. to the throttle Valve 83 in the intake manie 'fold to be operated upon movement of the latter, the connection being such that as the throttlevalve is opened, the valve controlling the-flow of the gases through the pipe -6 is. closed to limit the ow of the exhaust` 4gases therethrough. As diagrammatically shown in Figure 1, 845 is an arm connected to the valve 82, 85 is an arm connectedto the valve 83 and 86 is a tie rod pivotallyxcnncting these two arms together.

As'shown' in Figures 10,11, 12 and 13, the contact of a heating medium such as exhaust gases with a member containing `liquid particles other than the heating chamber of'an oil rectifying device may be controlled according to the velocity of the heating .medium to thereby control the heat to which .this member is subjected. In Figures 10, 11

and 12,87 is a carburetor, 88 an inta-ke maniold connected to the carburetor and' extending upwardly therefromf." 89 is a pipe adapted to conduct exhaust gases, the intake manifold extending through this pipe. 90 is -thedeiiector which is V-shaped and faces the flowof the exhaust gases and is located in advance. of andslightlyspaced from the 'intake manifold, this deflector being in the 'nature of a' rib preferablyformed integrally with the pipe 89, and extending parallel to the intake manifold 88. To additionally control the contact of the exhaust gases with ure 12 provided the'additional de'ectors 91, which extend inwardly from opposite sides of and slightly in .rear of the middle of the- A intake manifold and are adapted to prevent the exhaust gases -from passing 'inwardly toward the intake manifold when passing through the pipe at high velocity. I-Iow-` ever, when the .exhaust gases are passing through the pipe/ at a lower `Velocity some of these4 exhaust gases may pass between these deflectors and intake manifold. AS

shown in'Figure 13 the intake-manifold 92 extends transversely of the pipe 93 adapted for the passage of the exhaust gases and extends inwardly into a side of this pipe. 94

.haust gases with the` intake` manifold ydecreases.
